+Subject: btrfs: prevent __btrfs_dump_space_info() to underflow its free space
+
+From: Qu Wenruo <wqu@suse.com>
+
+commit 0619b7901473c380abc05d45cf9c70bee0707db3 upstream.
+
+It's not uncommon where __btrfs_dump_space_info() gets called
+under over-commit situations.
+
+In that case free space would underflow as total allocated space is not
+enough to handle all the over-committed space.
+
+Such underflow values can sometimes cause confusion for users enabled
+enospc_debug mount option, and takes some seconds for developers to
+convert the underflow value to signed result.
+
+Just output the free space as s64 to avoid such problem.

+
+Fix up a misuse that the filename pointer isn't always valid in

+Subject: net: hso: fix muxed tty registration
+
+From: Johan Hovold <johan@kernel.org>
+
+commit e8f69b16ee776da88589b5271e3f46020efc8f6c upstream.
+
+If resource allocation and registration fail for a muxed tty device
+(e.g. if there are no more minor numbers) the driver should not try to
+deregister the never-registered (or already-deregistered) tty.
+
+Fix up the error handling to avoid dereferencing a NULL pointer when
+attempting to remove the character device.

+Subject: serial: mvebu-uart: fix driver's tx_empty callback
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8

+
+From: Pali Rohár <pali@kernel.org>
+
+commit 74e1eb3b4a1ef2e564b4bdeb6e92afe844e900de upstream.
+
+Driver's tx_empty callback should signal when the transmit shift register
+is empty. So when the last character has been sent.
+
+STAT_TX_FIFO_EMP bit signals only that HW transmit FIFO is empty, which
+happens when the last byte is loaded into transmit shift register.
+
+STAT_TX_EMP bit signals when the both HW transmit FIFO and transmit shift
+register are empty.
+
+So replace STAT_TX_FIFO_EMP check by STAT_TX_EMP in mvebu_uart_tx_empty()
+callback function.

+Subject: xhci: Set HCD flag to defer primary roothub registration
+
+From: Kishon Vijay Abraham I <kishon@ti.com>
+
+commit b7a0a792f864583207c593b50fd1b752ed89f4c1 upstream.
+
+Set "HCD_FLAG_DEFER_RH_REGISTER" to hcd->flags in xhci_run() to defer
+registering primary roothub in usb_add_hcd(). This will make sure both
+primary roothub and secondary roothub will be registered along with the
+second HCD. This is required for cold plugged USB devices to be detected
+in certain PCIe USB cards (like Inateck USB card connected to AM64 EVM
+or J7200 EVM).
